  摘要：

  设计并制备了一类新型的手性双官能硫脲，该手性双官能硫脲带有手性亲脂性拜亚烷骨架和叔氨基。硫脲被证明可有效催化乙酰丙酮和硝基烯烃之间的双立体控制的不对称迈克尔加成反应。相应的加合物以高收率（最高95％）和良好至优异的对映选择性（最高97％）获得。此外，乙酰乙酸叔丁酯与反式-β-硝基苯乙烯的反应也顺利进行，具有良好的对映选择性。

  Novel supported chiral bifunctional squaramides have been easily prepared starting from diamines derived from natural amino acids and commercially available aminoalkyl polystyrene resins. These squaramides behave as excellent stereoselective recoverable organocatalysts in different Michael additions, in neat conditions at room temperature.

  Several novel chiral bifunctional L‐thiazoline‐thiourea derivatives were easily synthesized from commercially available L‐cysteine in high yield. These catalysts were subsequently applied to the enantioselective Michael addition of acetylacetone to β‐nitrostyrenes. The products with S configuration were obtained in 98% enantiomeric excess (ee) when the L‐thiazoline‐thiourea derivatives were used. A
